Matrix example

Matrix example tests

Installation

Make sure you are in the examples/matrix folder. In the terminal (Linux bash, Windows Cygwin, or Gitbash), run the following commands:

# creates the build directory
cmake -E make_directory build

# enters the build directory
cd build

# configures the build environment
cmake ..

# builds the project according to the configuration
cmake --build .

Usage

Program takes 2 parameters. 
First, you choose one of the following layouts:
1) rows
2) columns
3) z_curve (the size has to be a power of 2)
Then you input integer matrix size. 
The size of the matrix have to be at least one.
(for example simplicity, only square matrices are supported)

Running the example on Windows:

.\matrix.exe rows 7

Running the example on Linux or Mac:

./matrix columns 10
./matrix z_curve 8

Implementation

Implementation is commented on in detail. We recommend starting reading matrix.cpp, following with noarr_matrix_functions.hpp and z_curve.hpp last.

In file matrix.cpp basic matrix is implemented. Example first generates 2 classic matrices. Then it copies them into a noarr version. The example then performs multiplications separately. It then copies the noarr result into a normal version and compares the results if they are equal.

In file noarr_matrix_functions.hpp are implemented several matrix functions. The important function is:

template<typename Matrix, typename Matrix2, typename Structure3>
auto noarr_matrix_multiply(Matrix& matrix1, Matrix2& matrix2, 
    Structure3 structure)

it is given 2 matrices and it multiplies them, product matrix uses Structure3 as its structure.

You are able to choose from several layouts. The first two are modeled using basic noarr features. The third one is using z_curve implemented in z_curve.cpp.
